ii: i nown I. EDWIN C. LANE, u ciiizcn of thc United Shims, M151 2. resiticnt of Mahwah, in the coumy of Bergen and State of Ncw J'crscy, have invented a new anci improved FauBch; Adi s mcu'a, of which the fciiowiilg; is c fuii clear, and. GXZLQiZ description.

ifhis invention relates to suicmohiic acafui has pzu'ticuiar icicrcncc to 111 32118 for varying The tension upon the driving i .15; of s Tadistor fan.

Among the objects 01? the invention, thcrc is to provide :1 standard type of automobile, the mcchm nism com'px isin u iigid support in the 1m.-

otf lock screw having a hccd formed. in a pccuiiur mar or adapt for ihs ijusiuucni;

other parifis ung and oihsi ohjccts in chi.

'hcrcio mounted upon on com 16 pivoiic'ji as 1 .7 upcn cngiuc frame. The. hcit; 14 um'icr wr ing atmosphci'ic (,OfldltiOfiS or other circumstances incident to constant or ii'rcguhu' usage, is iikciy to hccomc loose and the, vesuit is many times fihc Fun is not pm.- If cic'ty. 1i iscrcforc provide a.

means for auizcmaticaiiy holding the h-sii', 14 under a degree. of tension. Thc means 1 cmplcy 101 if purpose inciucics a coil spring 18 liming as one and a hook 19 for engagement with the arm 16, and the othcr; and of the spring is cormccficci by suit-- chic means for val ing the: tension uponthc spying and through. i hc rcsiiieucy of which the igcnsion upon thc hcit is either controlled or adjusted. The action upon the belt is mainly automatic duo to the resiliency of the spring. and yct subject to adjustment so compcnsatc :Eor variations in cffcctivc length of the hcit time to atmospheric or other comdi'aicns.

The main rigid support is inciicntcd at 220, the smuc comprising a. binding ooit having a iiucndod shank 2i and a long poi'ygo uci head shown of hexagonal prisn'mcic "form. This sumiort 20 takes the piscc of one oi. the above mentioned lock 4 bolts serving i0 scours the hot Water pipe 12 to the. top of the engine. The stanchu'ci loci: hoit is removed when this adjustment device is to hc uataci' 51 to the machine and the shank portion 21 of the. new support is sci'cwcd into piccc. This support, therefore. scrvcs sii thc usimi functions of the sfionihu'd bin .11" ooit.

The. front or cc curl of hcuci is horcc'i aucsiiy f such. iiai; in is? J. (1 b n umtcriaiiy conirucied in circumference. Tho uuf 23 is 'ioru'icc'i also with a circumfci-cntini groove, in -which the oxtrcmc cnci coiis oi? tho spring are gripped 110i oni y" to hohi tho nut from yotaiion but to prevent any possihiiity of Withdrawing the nut from thc spring. After the supporting bolt 20 is screwed into place, i'ccstahiishinc' tight sumc' vertical ccn'ncccion hcizwccn ihc "pipe 12 anti thc c11 :nnt, The s ggine inc-net, one er the list faces of the head ill practical of :1V long screw 52 then inserted into that in e which l es ifs axis In alinement with l the axis of the coil and she threaded end the scren made to connect with the 23. Slime the hook 19 embraces the 16 hold the spring from. rotation mound its rotation l) spring, a sore driver an iron oil? oil ermine {he fles'ree of tension necessary "so to m belt. Fig, 1 shows the i plowunder a certain degree ,tch or clue to the cooperation bot-Ween the screw and the non-rotary w ,1 of the spring proporionel to the ordinary tension desired to be placed automatically upon the belt, anal therefore the r ne the spring is such as to mains 'n is proper degree of tension upon the ox izl'iongh the belt ipself may be adjusted lo compensate for varia- Mrlne'coc er or usage. When it or line Womb rferent oon-.

is required, however, to tighten the belt, a few turns of the screw will suffioe.

The device is simple, convenient, eas of attucinnenc, and when once attached, is perfectly and reliable in use and is not only nest in appearance one does not obstruct or endanger any other parts of the nmchine.

l claim In a fan. belt adjustment for motor cars, the combination with the hot Water 'pipe and ilie engine body, of a bolt, to connect the pipe to the body, said bolt comprising a long prismatic rigid support Whose outer encl has a 'plnralisy of holes forme clie- 'wnereby one end of the spring acts upon the boli, and a, nut secured to the other end of the spring and adapted to recelve the free end of said threaded connection.
